BLUE LIGHT-EMITTING COIL-ROD-COIL BLOCK OLIGOMERS WITH RIGID p-HEXAPHENYL AS CHROMOPHORE

Received Date: 9 March 2005
Revised Date: 28 May 2005

The synthesis and characterization of coil-rod-coil triblock oligomers，poly(ethylene oxide)-b-p-hexaphenyl-b-poly(ethylene oxide), are described. The number of repeating ethylene oxide units in each flexible block are 3 (EO3-PHP-EO3), 8 (EO8-PHP-EO8), 13 (EO13-PHP-EO13), and 17 (EO17-PHP-EO17), respectively. The structures of these oligomers are confirmed by 1H-NMR, 13C-NMR, EA, and MALDI-TOF mass spectrometry. The introduction of soluble poly(ethylene oxide) coils to the rigid p-hexaphenyl segment significantly improves the solubility of the oligomers, so they can form smooth thin films by spin-coating from their solutions. The oligomers are quite thermally stable and have 1% weight loss temperatures at above 340℃ under nitrogen. They can emit strong blue light in both solution and film state, and have fluorescence quantum yields of about 40% in chloroform. They are expected to have potential applications in optoelectronic devices.
